Howdy, The search function does not appear to be working for me today. Non the less, I know several threads in the past have dealt with making bows from autumn olive or its close relative , russian olive. Results have varied, but usable bows are possible. Russian olive wood is dense, with beautiful heartwood and I suspect the same is true of autumn olive. Reports also say the wood tends to be brittle and difficult to dry without checking or splitting.
